LONDON — A grass fire here that burned about an hour and a half was contained at 1 p.m., officials said.

Pope County dispatchers said rural fire departments from London, Crow Mountain, Linker Mountain and Bayliss Township and the Arkansas Forestry Commission responded to the fire, which spread about 20 acres before it was contained.

Pope County Judge Jim Ed Gibson was at the scene and said no structures were damaged.

The cause of the fire is not known.

Tuesday's fire is the latest in a rash of local outbreaks, which included a wildfire north of Atkins earlier this month that burned more than 500 acres and forced the evacuation of several homes, although none of the 144 structures threatened were lost and no one was injured.
